FEED-WATER PU RIFI ER.

SPECIFICATION forming part of Letters Patent No. 528,512, dated October 30, 1894. Application filed July 9, 1894i- Serial N0.'516,966. (No model.)

To all whom it may concern:

.I Se it known that I, STERLING L. BA1LEY,a cltizen` of the United States, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in Feed-Tater Purifiers, of which the following is a specification.

My invention relates to feed water purifiers for use with boilers, and the' invention consists in anovel construction of the apparatus, whereby 1t 1s rendered more effective and capable of being more readily taken apartl forcleanng or repair, all as hereinafter described.

Figure 1 is asectional perspective view of the apparatus ready for use. Fig. 2 is ahoriaontal section on the line .1s-x of Fig. l, looking from above downward; andFig. 3, a perspective View of adjoiningtubeheads, partly duce the best results, unless the apparatus sented in Fig. 1.

be made of'an unnecessarily large size.

The object of my ieveution yis to remedy these objectionsor difficulties, and to produce an apparatus which shall be small and compact, and yet have sufficient surface ofi-the requisite metals to act with efficiency upon the Water, and the internal parts of which can be removed and replaced without difficulty whenever required, either for cleaning or for renewal of the parts, Y'

In the drawings A represents the case, which may be of cast iron, with heads bolted on as shown, the heads beingtapped for the reception of an inlet and an outlet pipe, as repre- On the inner walls of this case I provide lugs o, 'three or more, to support the internal parts, these lugsbeing cast 'with the case or secured thereto in anysuitable manner. Within this case I arrange a series of zinc and copper pipes a and b in two or more circles (according to the diameter of the case) as indicated in Fig. 2, there being asmanyof these tubes as can be ar ranged within the case and allow free space for the water to pass between and through them. These tubes are held in place by means of zinc plates at top and bottom, the bottom ,plates B and B being shown clearly in Fig.

2. If these bottom plates be'cast separate, there will be arms or projections n cast on one or the other as shown in Fig. 2, in order to hold them and the two rows of tubes concentric. It is,-.however, obviousthat they vmay be casttogether as one plate, theinner and outer portions being connectedby the arms n. On their upper faces around each= tube hole, is an annular projection orcollar e, of the proper size to permit the tubes aand -b to fit over them as represented in---FigsgI and 2. At their upper ends these tubes, if made continuous and of full length, as they obviously may be, arevheid by a similar zinc plate or plates, reversed so as to have the collars e on the under side for receiving the upper ends of the tubes, all or a portion of the tubes being soldered at their ends vto the plates so as to hold the parts together and enable the tubes with their plates to be handled with ease and without separating.

The tubes are alternately of zinc and of copper, or of other metals that are. relatively electro positive and negative, @indicating the Y zinc tubes and b the copper tubes. Thus far I have described these tubes as being' continuous from end toend, but I prefer to make them up in sections, three sections being' shown vin Fig. l, each section ordinarily being six or more inches in length, andthe tubes a half inch or more in diameter. Whenv thus: made up in sections, the upper ends ofv ther lower `group of tubes are held inplace by a zinc plate C, `Fig.'1,'which` has the projecting collars e on both faces, those on thelower face'to receive the upper ends of the tubes, and the collars on the upper face serving to' tit into circular recesses in the' bottom plate D of the group above, as shown in Fig. 1,' the second and third groups being united in the same way.= One advantage of making them in sections is that the tubescan be so -ar'- ranged that the copper tubes in one group can be made to coincide axially with thev zinc tubes of the next group, and'so on continu-.-

ously with all the groups, so that the water passing from bottom to top passes first through a tube of one metal in one group, then through a tube ot` the other metal in the next group, and then througha tube of the same metal as in the first group, as shown in Fig. 1, where, as previousiystated, a indicates th'e zincand b the copper'tubes. Of course the same effect is produced upon the outer V.surfaceof the tubes at the same time, inas much as the tubes resting onthe brackets o have a space between the tubes and the inclosing case, through'which the water has free circulation, passing thence among and around all the tubes. By this construction and arrangement, and owing to the large amount of surface of the zinc and copper brought into contact with the water, the galvanic action is greatly increased, and thus a Very effective apparatus can be produced of small size. Y y

lrVhen necessary to clean .the purifier, orto renew anyof the parts, it is only necessary to remove thetop plate and lift th e.-sections out successively. Being separated from the case, corrosion and sediment do not interfere' with their removal` as with apparatus now in use.

' To replace the parts it is only necessary to set the first or bottom section on the supports o,then place the secondon that, and the thirdl on the second, they fitting together as described, so that they are held securely in place Without other contact with the case than Where the lower section rests upon the lugs or brackets.

It is obvious that this construction is applicable to al1 sizes required, and that if desired, the number or the length of the sections may be increased.

Copper and zinc are named as the preferred metals because of their efficient action and Atheir cheapness, but it is obvious that other` v relatively electro-positive and negative mety other well known couples.

als may be used, such as zinc and lead,sinc and iron,zinc and tin,-iron and copper, or

So too, I have described the heads as formed with nipples, or with nipples and sockets, but it is obvious that sockets alone may be provided and the ndsof thetubes be inserted directly therein.

Finally,'it is not essential that the heads Bf B', C and D be made of zinc, as other metals will answer, but I prefer zinc because of its superior action with the copper tubes.

I-Iaving thus described my invention, what I claim isv 1. In a Water purifier, the combination of an outer shell provided with a removable cap,and a'series of relatively electro-positive andnegative Itubes loosely mounted within the shell and freely removable therefrom. f

e 2. `In a water purifier, the combination with an outer shell, of a removable interior body composed of tubes of relatively electro-positive and negative metals, and connecting heads thereforffand supports for said body within the shell.

3. In a water purifier, the combination with an outer containing shell, of an internal tubular body, composed of separable sections each comprising a group of tubes oE relativelyl electro-positive and negative metals.

4. The herein described water purifier, consisting of au outer shell A provided with internal lugs or projections o, and a removable internal tube system comprising tubes a and b of relatively electro-positive and negative metals, connected by heads B.

5. In combination with shell A, a'sectional internal tube system, consistingof tubes a and b of relatively electro-positive and negative metals, arrangedin groups, each group 4being provided with 'connecting heads, the llower head of one group being adapted [to tit' `upon the upper head of the next lower group,

substantially as shownand described.

6. In a Water purifier, the combination of a shell A, and a sectional tube system of relatively electro-positive and electro-negative metals contained therein, the trbesbeingarranged in groups, and the groups vbeing provided at their proximate ends with heads C and D, respectively furnished with nipples and sockets in axial alignment with the tubes, whereby the groups are held in proper relation.

7. In a water purifier, the combination with an outer shell, of an internal'tube systemof relatively electro-positive and negative metals, said tube system being' provided with heads having annular openings, and being of less diameter than the shell, whereby free passage for the water is afforded between the sh'ell and heads and through the heads.

vIn witness whereof I hereunto set my hand rc5 in the presence of two witnesses.
